Electrical connector assembly

Abstract

An electrical connector assembly comprising a base defining a plurality of passageways and a conjugate member, a plurality of terminals residing in corresponding passageways, and a pick up cap being detachably mounted on the base and defining a conjugate post. The conjugate member having a hole and the conjugate post having a plurality of interferential robs for abutting against the interior wall surface of the conjugate hole. With this configuration, there is a reserved space to hold the plastic scrap produced by the conjugate post and the conjugate hole when the electrical connector is mating with the pick up cap, so that the pick up cap can be easily mounted on the electrical connector.

1 . An electrical connector assembly comprising:
 a base defining a plurality of passageways and a conjugate member, the conjugate member having a hole;   a plurality of terminals residing in corresponding passageways, respectively; and   a pick up cap being detachably mounted on the base and defining a conjugate post, the conjugate post having a plurality of interferential ribs for abutting against the interior wall surface of the conjugate hole.   
   
   
       2 . An electrical connector assembly as defined in  claim 1 , wherein a recess is provided to traverse the post. 
   
   
       3 . An electrical connector assembly as defined in  claim 2 , wherein the conjugate post has two ribs. 
   
   
       4 . An electrical connector assembly as defined in  claim 3 , wherein the conjugate post is formed as a column configuration and the ribs are symmetrically disposed on the post in a diametrical direction. 
   
   
       5 . The electrical connector assembly as defined in  claim 1 , wherein the base comprises a pair of ridges on opposite sides of the conjugate member and the pick-up cap defines a pair of engaging projections on opposite sides of the post for engaging with the ridges. 
   
   
       6 . An electrical connector assembly comprising:
 an insulative housing including a center portion with a hole therein and a plurality of passageways symmetrically located by two sides of the center portion;   a plurality of contacts disposed in the corresponding passageways, respectively; and   a pick-up cap including a suction plate with a post extending downwardly from an undersurface thereof; wherein   at least one of said post and said hole is equipped with a plurality of downward ribs around a periphery thereof for interferential engagement with the other.   
   
   
       7 . The assembly as claimed in  claim 6 , wherein the post defines a recess extending downwardly in communication with an exterior 
   
   
       8 . The assembly as claimed in  claim 6 , wherein the hole extends through the center portion. 
   
   
       9 . The assembly as claimed in  claim 6 , wherein the ribs are formed on the post. 
   
   
       10 . The assembly as claimed in  claim 9 , wherein a bottom end of the rib is higher than a bottom end of the post so as to assure an easy initial coupling between the hole and the post before the rib is interferentially engaged within the hole.
